The principal object of the present invention,

is to provide a molder which may beused in pro ducins aments ma e fr m pl i s Q di ierenti colors o ad s f o o s, and. Where r sulting product will be highly satisfactor and attractive in that unintentional extruding of more of one color or shade. of color than of; the other may be easily avoided. In a practical use of the molder, flowers (such as roses by way. of; example, having petals of one color or shade on one side and a diiferent color or shadeonth e other side), may be imitated in a manner so that it is diiiicult, without close inspection, to distinguish the imitation from the real article.

Other objects of the invention are to produce molders which may be easily cleansed, may comprise a number of diiferent types, of nozzles, any

of which may be easily and quickly attached tothe containers, and which may bemanufactured at a low cost so that the invention may be brought within the meansof avast number of users who may practice the decorating artand:

use the molder as described herein.

molder in accordance with my invention is illus-. tratedin general as applied to a type of dis.

pistpn I I particularly well adapted for dispensing plastic .pastry material for use in decorating cakes, and the like. The casing has an upper head end. member 12 with lateral finger eration with an operator mounted on the outer end of piston rod [5 on.

the; inner endof; which piston II, is mounted; On the other end of cylindrical casing II). a cone nector head I6 is mounted for the mounting of material is ejected in a decorating process.

While dispensers of the general characteristics. abovedescr-ibed have been in general use, as well.

as those generally comprising a flexible bag or container equipped with a nozzle of which the invention disclosed in my aforesaid application,

is an improvement, the pre-ent invention em-, bodies improvements applicable to each of said types.

In the usual form of such cylindrical casing dispensers, the matter of c'eaning and assembling of-the partshas been a problem whch is simplified in accordance with improvedconstructiqns in accordance with my invention. 'lhecyl Fig. 3. is a longitudinal vertical sectional views M in theform of a ring,

inder casing Ill in accordance with my invention is a plain but sturdy cylindrical tube without threads at its ends which become clogged with plastic material. In place of such threads I employ bayonet joint type of connections 18 for both heads l2 and [6. As best shown in Fig. 2, each end of the cylinder has three equally spaced bayonet joint projecting lugs [9 for cooperation with three bayonet joint slots 26 in each of the head members, i2 and It. Thus the head members fit interchangeably on the ends of cylnder I and it is immaterial which end of the casing is positioned at the top, the casing being otherwise perfectly plain except for a single index mark 2| at each end midway between a pair of the lugs l9 as a guide for couplng head It which has a corresponding index mark 2| thereon and the positioning of a partition member 22 in the casing. Such index marks are employed solely for the positioning of the partition 22 in the casing as will be subsequently explained.

The upper head member l2 has a concentric bushing 23 providing a bearing thru which piston rod extends and is free to turn and reciprocate, and operating ring id is secured to a collar 24 when is removably secured on the piston rod 15 by means of a set screw 25 altho it may be otherwise or permanently secured in place after the head i2 is once in position on the piston rod 15 as the subsequent disassembly of this operating member from the piston rod [5 is not essential. Piston rod I5 has a longitudinal slot 25 therein extending from a po'nt adjacent to its upper end corresponding with the top of casing l0 when piston H is in the bottom thereof and entirely thru piston ll thereby bifurcating the piston and its rod so that it will straddle parti tion 22 when it is inserted in casing id.

Partition 22 has a width substantially the same as the internal diameter of cylinder casing Ill and is generally rectangular in shape so as to divide the cylinder into two compartments of substantially equal volumes. When positioned in the cylinder with the nozzle head it in position its lower corners 21 and portions 255 seat against the inner face 29 of head it. Partition 22 has an integral extension shaped to conform with the inner surface 3! of the reduced cyinder portion 32 of head l6 and for a distance downward in nozzle il short of the lower end thereof as best shown in Fig. 3. In my earlier application the corresponding partition extends integral'y with and to the open end of the nozzle. However as an improvement the partition 22 herein is removable as a unit and by having its lower end 33 above the nozzle openng 35 plastic confectionery materials of different colors in the two compartments 35 and 36 of casing l6 are brought into intimate contact so as to unite without mixing to any substantial degree before they are ejected from the nozzle opening 3- 1.

Nozzle I! for illustrative purposes has a lower dispensing jet formation 3'! s miar to that disclosed in my earlier application of concavo-convex construction for the formation of rose petals and the like as fully described and claimed in my said earlier application, tho other forms of dispensing jets may be employed w'th the present confectionery molder within the broadest scope of my invention. The nozzle IT has an upper cylindrical portion 38 for s'idinzly fitting the inner cylindrical surface 3| of cylinder portion 32 of head It. A pair of studs 39 for engaging n a corresponding pair of bayonet slots 40 in cylinder 32 which fix the position of nozzle H in- 4 cooperation with head I6 and the index marks 2! on cylinder [0 when these parts are assembled. Just below studs 39 nozzle I1 is formed with a manual manipulating collar 4| which also acts as an abutment for engaging the lower end of the nozzle head cylindrical portion 32. Below collar 4| the nozzle I! is shaped, flared laterally and curved to provide the elongated nozzle opening 34 for the dispensing jet formation 31 as referred to above.

It will be noted that in positioning partition 22 in cylindrical casing ID the index marks 2| define the position of the nozzle jet formation 3? with respect thereto and also the position in which partition 22 is to be inserted for molding rose petals having one color of the plastic confectionery material on one side and another shade or color on the opposite side, the partition extending into the nozzle so as to form the separate layers of uniform thickness in accordance with the arrangement set forth in the earlier application.

The present arrangement has numerous advantages over my prior arrangement. According to the present arrangement, as above set forth, the two layers of different plastics are positively united before leaving the jet. The partition with its lower extension extending into the nozzle is a single integral piece. If the type of molding nozzle applied to the head I6 is not of a character to produce ejections of ribbon-like formation, differently colored, but rather of any of the ordinary mo-ding nozzles such as for simulating rope, or where a ribbon-like formation having no difference in color at opposite faces is desired, care need not be exercised in accurately positioning the part'tion 22 and its extension 3!! with respect to the cylinder 16 and the molding nozzle ll.
